S5 E3 • Un train dans la nuit

The railway takes centre stage as Endeavour investigates the disappearance of a local woman - with initial fears linking it to the unsolved murder of a teenager, killed several years earlier. Endeavour puts the missing woman's last known movements under scrutiny, while Thursday is absorbed in the investigation of a lorry hijack which he suspects is linked to local gangster Eddie Nero. The murder investigation takes a surprising turn when a woman's body is discovered, but Endeavour notices anomalies at the murder scene which point away from the cold case theory. Meanwhile, Cowley is disrupted by the arrival of two rough-and-ready burglary squad officers, also investigating the lorry hijack, who commandeer Fancy for their plans. Soon stumbling on a potential informant, Fancy is thwarted when his new lead is violently killed. The discovery of another body uncovers a clue that blows the case of the missing woman wide open - and leads to an unlikely culprit.
